AWNIN G.

To all whom it may concern:

Be it known that I, LOUIS M. HALsEY, a citizen of the United States, residing in the city of New York, borough ofiBrooklyn, in the county of Kings and State of New York, have invented a certain new and usefulImprovement in Awnings, of which the following is a specification.

The invention relates to that class of awnings in which the duck or other awning fabric is attached at the lower margin to a bow pivotally connected at its ends to runners arranged to slide on guide-rods in the operation of raising or lowering the awning, and the object of the invention 1s to provide simple, inexpensive means for automatically engaging the bow-end, runner, and guide-rod and holding these members fr1c tionally in such relation as to prevent movement relatively to each other when the awning is in the lowered and unfolded condition, thus eliminating the annoying rattle due to such movement, and for releasing automatically by the folding movement of the bow 1n the operation of raising the awning.

The invention consists in certain novel features of construction and arrangement by which the above objects are attained,.to be hereinafter described and claimed.

The accompanying drawings form'a part of this specification and show two approved forms of the invention.

Figure 1 is a side elevation showing a portion of a guide-rod, runner and bow of the usual type, equipped with the invention.

Fig. 2 is a corresponding front view with the bow-end in transverse vertical SBCUOI'I:

Fig. 3 is a corresponding plan view, wlth the guide-rod in horizontal section.

parts in all the figures.

Referring to Figs. 1 to 6 inclusive, A is one of a pair of guide-rods mounted vertically as usual on the window or door frame and receiving a tubular runner B inclosing the rod and adapted to slide thereon. D is one of the bow-sockets having a tubular extension D adapted to receive the end of the bow C, and has a central opening of receiving an arm 13 on the runner B and is secured loosely and pivotally thereon by a nut E and washer F or other suitable fastening means.

The main portion D of the bow-socket is circular in form and has an annular rim or flange on the inner face surrounding the opening d, which is shaped to produce two oppositely located cams, and mounted on the arm B between such rim and the runner B is a friction plate G having legs Gr G bridging the runner vertically and presented adjacent the guide-rod at points above and below the runner. V

The spiral cams are so formed and located on the bow-socket D as to ride upon the outer face of the plate G and force the legs G G in the reverse direction and relaxes the frictional engagement sufficiently to permit the runners to move freely upward on the rods and the awning raised. as usual.

Each cam may be a simple spiral or incline but is preferably divided into three portions flowing each into the next, comprising a low portion D which may be plane and of sufiicient length to insure relaxation of the grip on the plate G when the bow approaches the end of its upward swing; a spiral portion D by which the tension is produced with gradually increasing force when the bow swings downwardly, and

gradually relaxed as it is swung upwardly; and a high portion D" which may be plane and permits the bow to complete its down- The arm B may be cylindrical through-f out and the opening 9 in the plate Gr may be correspondingly shaped, *but in order to preventdisplacement by rotation on the arm and to insure the proper presentation of the legs GFG to the guide-rod, it is preferable to provide a square or angular portion B on the :arm and to square the opening 9 as shown and thus insure positive engagement. The ends of the legs are notched as at g g to aid in maintaining the plate "in the desired position relatively to the rod, and by deepening the notches 9 such position may be satisfactorily maintained without employing the-squared portion 13 of the arm and the correspondingly shaped hole 9 1n the plate.

The above described form permits the 1nvention to "be applied to the usual awning fixtures with but little change of the latter, mainly the addition of the plate G and its notched legs G In the modification shown "in Figs. 7 and :8 the plate is omittcdand the cams, marked D D D coact directly with the surface of the guide-rod A "at pomts above and below the runner B The action and operation of this simplified form are 1n all respects similarto those of the "form'lirst described.

Other modifications may he made in the 7 details of the mechanism, such as the substitution of other fastening means for the nuts E and washer F, and in the forms of the cam surfaces in adapting the invention for various conditions of service.

1. The combination of a guide-rod and a runner slidably mounted'thereon, of a howsocket rotatably mounted on said runner and adapted to receive an end of an awning how, said socket having an lnclmed cam surface thereon arranged to effect an engagement of said rod hythe downward swing of sa1d bow in lowering the EUWI'HIIO.

2. The combination of a =guide-rod and a runner 'slidably mounted thereon, of a bowsoclcet pivotally mounted on said runner and adapted to receive an end of an awning bow, said socket. having oppositely locate bongsaid socket having a cam surface thereon comprising a substantially plane low portion, and "inclined portion, and a substantially plane high portion, said inclined portion arranged to e fiiectyan engagement of said rod by the downward swing of said how in lowering the awning, and said high portion arranged to maintain such engagement uniformly during the completion of such downward movement.

a 4-. The combination ot a guide-rod, and a runner slidably mounted thereon, lot a bowsocket pivotally mounted on said runner and adapted to'receive an end of an awning bow, said :soc ket having an inclined cam surrliace thereon, and means actuated by :said oam surface for engaging said rod by the downward swing of said bow in lowering the awning. r a 5. The .coirlbination o f a guide-rod, a runner slidably anountedtlrereon and having a projecting arm, a bow-socket pivotally mounted on said arm, means for holding :said socket on said arm, inclined rCElBl surfaces on said socket adjacent said runner, a plate mounted on said arm between said cam surfaces and said runner and arranged to engage or release said rod zby the action of said cam surfaces.

'6. The combination of :a guide-rod, :a runner slidwhly mounted thereon and having a projecting arm, bow -zsocket pivotally mounted on said :anm, means for holding said socket on said arm, inclined cam surfaces on said socket adjacent said runner, a plate mounted on said arm ibetaveensaid cam surfaces and runner and having leg-s "adapted to engage said trod above and below said runner by the action of said camesu-rfaces upon said plate.

7. The combination of ca guide-rod, arunner slidably mounted thereon andxhaving a projecting arm, a bOWrSOCkBt pivotally mounted on said arm, means for holding said socket on said arm, inclined cam surfaces on said socket adjacent said runner, a plate mounted on said arm between said cam-surfaces and runner and having legs adapted to engage said rod :aboveand below said runner by the action of said cam-surfaces upon said plate, said arm "having an angular portion thereon and said plate having a correspondingiopening therein receiving and matching to such angular portion.

8. The combination of a guide-rod, a runner slidably mounted thereon and having a projecting arm, a bow-socket pivotally mounted on said arm, means for holding said socket on said arm, inclined cam sure faces on said socket adjacent said runner, a plate mounted on said arm between said cam surfaces and runner and having legs low said runner by the action of said camadapted to engage said rod above and besurfaces upon said plate, said legs having each a notch partially inclosing said rod.

In testimony that I claim the invention above set forth I affix my signature.
